DOOR LOCK.

Application led September 8, 1923. Seriafl No. 661,580.

To all whom t may concern:

Bc it known that I, FRANK BRABSON, a citizen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Door Locks, of which the following is a specification.

This invention relates in general to door locks of the type comprising two longitudin-ally alined bolts or locking rods secured to a door or the llke to cooperate with keepers on the door frame, and means including a knob or handle arranged between said bolts for simultaneously moving said bolts longitudinally in opposite directions to engage with or disengage from said keepers to lock or unlock the door. The bolts of such looks are several feet long and extend the full length of a door or swinging window, and much diliiculty is usually encountered in applying known locks ot this character to a door due to the fact that the bolts must be first secured to the operating mechanism or knob and the'whole lock as an entity secured to the door. Two men are usually required for this purpose, one to steady and position the device while the other astens the same in position.

The primary object of my invention is to provide a locking mechanism of the character described embodying novel and improved ieatures of construction whereby the mechanism can be easily assembled, located on and secured to a door piece by piece by one man.

Another object is to provide such a lockving mechanism embodying novel and improved operating mechanism :tor the bolts which can be easily and quickly positioned grid secured on a door and connected to the olts.

Further objects are to provide a locking c in which like numerals of reference designate the same parts throughout the several views,

Figure 11 is a top plan view of one of the keepers on the frame of a door to cooperate with one ofthe locking bolts, and

Figure 12 is a vertical longitudinal sec tional view through a part of the door frame and the keeper.

In the specific embodiment of the inven tion shown on the drawings, the reference character A designates the operating mechanism of the door lock embodying the invention which cooperates with locking bolts or rods B arranged in substantially longitudinal alinement to slide longitudinally of the door in guides C, said bolts cooperating with keepers D secured in the frame ofthe door. When the bolts B are in engagement with the keepers D the door is locked, and when the bolts are moved longitudinally by the operating mechanism A out of engagement with the keepers D the door is unlocked.

The operating mechanism includes a base section l preferably formed of sheet metal and having substantially centrally of its length oppositely disposed upturned flan es 2. The ends of the base section are provi ed with prongs or points 3 which may be convenielntly stamped from the metal of the baseQand substantially centrally of 'its length the base is provided With an opening 4 to form a bearing for an operating knob or Y5 handle 5'; The operating `handle ror knob includes a handle portion and a shank portion 7 which is rotatably mounted in an upper casing section 8 to cooperate :with the base section l to form a housing for the 10 operatingmechanism- The inner-end of the shank 7 has rigidly secured thereto a pinion'9'to-'cooperatewith racks 10one formed kat one end of each of the locking Abolts Bu -The locking bolts B are preferably `formed '15 of' substantiallyy halt roundcmetal and the rack l0 oteach of therods is laterally offset in a direction opposite to Ithat of the rack of the other rod, yas clearly indicated in Fig- *mures 4, Wand l0. -The said racks lmay be 204cast integral Vwith the rods B 'or lformed sepa-`v rately and-rigidly secured thereto as by -f riveting.`l-The-inner ends of the racks are -io'rmed'vvith shoulders 11 for a *purpose hereinafter described. The outer ends of the vbolts Bfarey-forned Withxtransverse openings /12'Which' are preferably located on the f" bolts at the position Where the guides C en- '"lygage-'thel-bolts. The guides C for the rods -f arepreferablytubular in construction so as to slidablyreceive the rods and guide them in their longitudinal movement on thedoor.l In-assembling and applying theloclr to af KAdoor, a 'shallow recess l13 is formed in theV door at the position Where it is' desired to 35 .place the operating mechanism AL The base section 1 Iis then applied to the door with the opening 4-substantially registering with the A 'recess 18 fand the flanges 2-projecting outi wvvardly fromvthe door'and extending longi- 40 t-udi'nally-thereof.' Thefends of the base sec` Ytion-- are -then'tapped as with a hammer to embed the prongs' 3 inxthey door, the said f prongs'thenholding the base section in positionE The-bol'tsB are-then separately api plied to the door with the outer-end of one 'rack abuttingthe shoulder 14 formed at the adjacent end e'of the otherrodffand 'with the ".-zlin'ner ends of the 'racks-positioned-substanefltially ,equidistantlyfromthecenter of the V opening-4 at oppositef'sidesthereof." The if, racks are also in engagement 'with the cor- V- f Vresponding:flange 2 of the-:base section, and f the-bolts may bei/heldy inlrthis position by `Ladriving:nails orthe like 15- through the openings 12 intothe=-door.
